Lactic Acid
Lactic acid (2-hydroxypropanoic acid) is an organic acid produced by bacterial fermentation of carbohydrates. It is a colourless to pale yellow syrupy liquid, fully miscible with water, and exists as L(+), D(-) and racemic forms - the L(+) isomer being the one the human body metabolises and therefore the food and pharmaceutical grade. Its combination of mild acidity and antimicrobial action is what distinguishes it from the stronger mineral acids.

Application / Intended Use
Lactic acid is used as an acidity regulator and antimicrobial. Meat and poultry processors apply dilute solutions as a carcass decontaminant; bakeries use it for sourdough acidification and dough conditioning; the beverage industry uses it for pH adjustment where a milder, less sharp acidity than citric is wanted. It is also the monomer for polylactic acid and a descaling agent in dairy CIP.
